A Mac OS X screensaver with live footage from the International Space Station.
Notes from the Ustream Channel:
Black Image = International Space Station (ISS) is on the night side of the Earth.
Gray Image = Switching between cameras, or communications with the ISS is not available.
No Audio = Normal. There is no audio on purpose. Add your own soundtrack.
The above means that you will have a black or grey screen for ~45 minutes since ISS makes a full orbit every 90 minutes (=45 sunsine, 45 night). But the sunsets are magnificent up there..
You can grab the Release/ISS Screensaver.saver and simply install it.
Posibibly add a map with the location of the ISS as shown on the second map on this page. Feel free to push your requests.
